Title: Crossbar switch for telephone exchanges - has contact springs at intersection points each with one make and two break positions
Inventor: HILLIGES FRIEDRICH
IPC: H01H67/26
Filed: 1976-07-12
Abstract: The incoming lines of the switch are crossed in a coordinate manner by outgoing lines. Both types of lines have associated, adjustable selector and switching rails. At the intersection points are coupling contact springs whose free ends engage in selector and switching rail recesses. Each contact spring (F) has a make position (R) and two break positions (Rw, rs). The recesses in the selector (W) and the switching rails (S) actuate the movement of the spring contacts from the two break positions into the make position, on actuation of one of the rails. When only one rail is actuated the spring contact in the make position is moved into the respective break position. The location of the recesses in the rails safeguards the maintaining of the respective contact spring positions.

Title: Rotary IC engine - has three rotors carrying vanes along length of shaft and with differential gear between them
Inventor: DOUNDOULAKIS GEORGE J
IPC: F01C1/073
Filed: 1977-04-29
Abstract: The engine has a shaft on which a central disc is fixed, to form a central rotor which carries two pairs of blades, one pair of projecting on each side. There is a side rotor on each side of the central rotor. The side rotors run on bearings on the shaft and are driven through a differential from the central rotor so that the rotation of the central rotor is the average of the rotations of the side rotors. The working chambers are formed between the outer stationary casing and one blade of each of the central and side rotors. The arrangement is such that as one chamber increases in volume the next one decreases in volume. The outer casing is cylindrical.

Title: Hot bending brittle material without cracking - by heating surface of workpiece to above embrittlement temp. range before bending
Inventor: HEGEWALDT FRITZ DIPL ING
IPC: B21J1/06
Filed: 1977-06-22
Abstract: Surface cracks are avoided during the hot-deformation or -working of materials which exhibit brittleness at high temp. by heating only a thin surface layer 10-15 mm. thick to above the temp. range in which embrittlement occurs, prior to the hot deformation treatment. The heating of the layer is pref. achieved by induction, using high surface power with a frequency providing a penetration depth of 10-15 mm. Used e.g. for the bending of continuous material, such as alloy steels.

Title: Speed reduction gear with primary and secondary sections - has balls giving one to N plus one reduction ratio
Inventor: YAMASHITA TOSHIO
IPC: F16H13/08

Title: Injection fluid retention system for bore in rock - has springy plate locking device and sealing sleeve combined with injection device
Inventor: ZEISSIG ORTWIN M
IPC: E21B33/126
Filed: 1977-07-15
Abstract: The system is used for retaining fluid injected into a narrow bore in rock, and incorporates sealing and locking devices. The sealing device consists of an elongated sleeve, expanded against the walls of the bore by the pressure of the fluid. The locking device consists of a springy metal disc (18) fixed to the central shaft (7) by nuts (15, 16) and bent back towards the mouth of the bore. It is easy to insert the device but the disc digs into the walls of the bore preventing withdrawals. The central shaft (7) is hollow, and its outside is threaded to take the nuts holding the sealing and locking devices. The injection fluid is pumped in through the hollow shaft and passes through bores (26, 27) and forces its way past a sleeve (25) which acts as a one-way valve.

This restoring unit comprises an electromagnetic. The shaft is fitted with a back stop. A pick-up unit (4, 5) is provided to indicate the consumption of paper from the roll.
Patent DE-2741683-A1 (DE)
Title: Planar diffusion for silicon planar transistor prodn. - comprises pre-diffusion into base zone and final phosphorus diffusion for emitter zone prodn.
Inventor: HERRMANN HANS DIPL ING
IPC: H01L21/225
Filed: 1977-09-16
Abstract: The transistor emitter zone is produced in its base zone by a predifusion process, followed by phosphorus diffusion through an emitter aperture. The doping in the emitter zone prediffusion layer is so far reduced as to meet a specified formula, giving a given ratio after the prediffusion. The formula relates to the emitter-base junction and to a measured layer resistance. Thus harmful grid voltage in an NPN planar transistor, forming part of an integrated circuit are avoided in a simple manner.

Title: Emergency repair kit for defective tyre - uses self setting plastics foam applied through nozzle into tyre
Inventor: WEBER RUEDIGER DIPL ING DR
IPC: B29D30/04
Filed: 1978-08-16
Abstract: The emergency repair kit for the tubeless tyre has a simple pressurised bottle with an insert nozzle which is pushed through a hole in the tyre wall to inject a self setting plastics foam. A second hole in the tyre wall allows excess air to be expelled. The wheel can be used for long enough to drive to a repair centre.

Patent DE-2842437-A1 (DE)
Title: One-piece, flexible, plastics bellows prodn. - by sliding widened tubular film over spaced-apart rings, heat-shrinking film to fit on rings and contract to bellows shape between rings
Inventor: BOHLMANN KARL-HEINZ
IPC: B29C61/02
Filed: 1978-09-29
Abstract: Mfr. of plastics, flexible, bellows comprises inflating or otherwise expanding a plastics tubular film or hose to up to six times its initial dia.; slipping it over spaced-apart rings; and then causing the tube to shrink by application of heat. In this way the tube sits tightly upon the rings whilst shrinking to a comparatively smaller dia. in those zones intermediate between adjacent rings, thus forming a bellow shaped, one-piece structure. The process enables bellows to be made in one piece without recourse to comparatively expensive moulds. The rings may be arranged e.g. in an acurate line so that curved bellows can be mfd. The rings are axially displaceable.
